What type of DWV PIPE used in Canada

Hi ,
I am going to do a small washroom reno and was wondering what type of 3 inch DWV pipe should be used in the DWV system above the basement concrete floor, ABS OR PVC . I have 4 inch PVC under the concrete. Located in Ontario, Canada.

QUOTE=mikeplummer;366388]we generally use ABS for anythign above ground in a residential building[/QUOTE]
In Ontario, can we use ABS underground ? for example, building drain (horizontal sections underground) can be ABS or have to be PVC (white or green in color) ?
